Abstract: An optical emission microscopy system comprises a macro optic system (30) having a high numerical aperture for obtaining global views of an integrated circuit device under test (10). The device under test (10) is subjected to illumination and stimulation conditions, and images are obtained to form a "global difference" image in which defects, wherever located in the chip, can be discerned by the system operator. The operator can select apparent "defect bright spots" to be further inspected, and zoom in with a higher magnification micro optics system (40) to repeat the image formation steps. "Difference images" are processed to further eliminate noise spots using an approved two-stage filtering operation. The system may be operated under manual or automatic control, and may be interfaced to various data input, storage, and output device as desired.

Abstract: A fast axial flow gas laser apparatus comprising an at least essentially closed loop defining a flow path for a laser gas, an arrangement for exciting gas flowing in the loop of the apparatus to cause the gas to lase, and a regenerative compressor for flowing gas through the closed loop along the flow path. The compressor is capable of operating with a pressure ratio sufficient to flow the gas along at least a portion of the loop at a speed at least half the speed of sound in the gas with inlet pressures of only a small fraction of an atmosphere. The uniform discharge pressure of the compressor results in a uniform laser discharge or output. A positive pressure fluid pressure seal prevents lubricant at a bearing support for the impeller shaft of the compressor from moving to the impeller and possibly contaminating the laser gas being compressed thereby and also prevents surrounding air from contaminating the laser gas. The pressurized fluid of the seal is permitted to migrate into the laser gas as make-up gas. The compressor is capable of moving gas through the laser at speeds approaching the speed of sound for high power output from the laser without power fluctuations and with minimal service requirements and long life while occupying only a small area within an existing laser cabinet.

Abstract: Machine à décharge électrique à fil de coupe destinée à soumettre une pièce à usiner à un usinage par décharge électrique, utilisant une électrode fil standard possédant un diamètre supérieur ou égal à 0,1 mm, par exemple, mais permettant d'utiliser une électrode fil mince d'un diamètre inférieur à 0,1 mm. Une électrode fil mince (43) présente une faible résistance à la traction due à son faible diamètre, de sorte qu'il n'est pas possible d'utiliser le même dispositif de manipulation de fil qu'on emploie avec les électrodes fil standard. Afin d'éliminer cet inconvénient, un dispositif de manipulation de fil destiné à être utilisé avec une électrode fil mince est monté à proximité d'une unité guide-fil inférieure (11), et on règle la force d'enroulement de fil de ce dispositif pour qu'elle soit suffisamment plus faible que la force de traction de l'électrode fil mince (43). Cet agencement permet de manipuler une électrode fil mince (43) sans quelle ne se casse. L'unité guide-fil inférieure (11) peut également être utilisée avec une électrode fil standard, et elle est remplacée en cas de besoin par une unité guide-fil inférieure correspondant à une électrode fil mince.
